In fact you wonder why Channel 4 didn’t just put Krishnan in charge of the 7pm news in the first place.

No, not really. At least not the news thing. For he truly was clobbered in the name of research for Drugs Live: Cannabis On Trial.

The second instalment of a desperate-to-be-controversial beast that had Snow clawing around to justify why he took hash and the stronger skunk for the two-year clinical trial: “I didn’t feel I could anchor a programme like this without doing it.”

Odd, then, that he felt he could anchor C4’s Drugs Live: The Ecstasy Trial in 2012 without touching the stuff.

This time, though, Snow was trumpeting “a series of world firsts”, like the earth-shattering finding that dope can leave users wanting a bit of a rest.

And his announcement: “We now know why music can sound more pleasurable when you’re stoned.”

Thank you, science. It was worth postponing the battle against ebola.

The irrelevance was lost on them.

As was the very obvious problem in Dr Christian Jessen inviting viewers’ tales of memory loss from cannabis, and the overwhelming pro-legalisation bias that gave only fleeting airtime to those against. (Well, they’d booked Richard Branson, you see.)
